What is a document camera ? Document cameras are fast replacing overhead transparency projectors as a way to display visual information. They employ a small video camera mounted on a stalk above a flat surface illuminated by a light. The image they capture is usually projected onto a screen.
What can Doc Cams do? Enlarge objects Zoom into specific areas of objects Capture images Freeze frame Manipulate images (flip images, black/white, etc.) Microscope Option ($28) Switch source from computer to doc. cam. –Need correct cords. Allows students to collaborate
How are they different from overhead projectors? Require opaque rather than transparent images Allow the display of three-dimensional objects Are typically Auto Focus, but allow manual zooming towards and away from images Usually employ digital technology so they produce images for display on a TV, monitor, data projector or via video conferencing Operate on a slight delay so blurring can occur when images or things under it are moved quickly Have special features like saving images and video to a computer
Benefits of Document Cameras Facilitates demonstration Students can share work in an efficient and effective manner Increases student participation and ownership in their work Easier to take advantage of classroom and text materials Assists visual learners Decreases prep time… no more transparencies!!!
What to Look for in a Doc Cam Focus Frame Refresh Rate Output Resolution Flexible Viewing Zoom Branzburg, Jeffrey. "Picture Perfect". Tech & Learning October 15, 2008:
Maintenance Turn bulb off when not in use Clean filter if needed (will prompt) Keep covered when stored – slide black bag over the top of the camera when not in use.
Tips for using a document camera Avoid using glossy paper (most doc cameras come with an anti glare sheet if too much light is reflecting off of a book page or other shiny surface) Using a cover sheet or the zoom tool to focus attention Use a pen to point at something under the document camera instead of your finger to prevent your hand from covering part of the object
Doc Cam Ideas Show writing samples, annotate while class views Model note-taking Use comic strips for startup. Cover last balloon. Kids create punch line. Show dioramas or other student 3D projects Roll dice Magnify $- note tiny owl top right corner, year 1776 in Roman bottom of pyramid, E Pluribus Unum around new coins edge, usmint.gov Picture books become Big Books Show maps or graphics from textbook
More Doc Cam Ideas Print maps from Internet then annotate Tape butcher paper on wall. Project maps/graphics, write on butcher paper to annotate instead of marking on original map/graphic on doc. cam. Find difference in two almost identical photos Baking soda, vinegar, raisins, water – chemical reactions experiment- use freeze frame to show beginning and end since you can’t get back to original form Pour bleach on fabric. Shows chemical reaction. Use freeze frame or take.jpg to show before/after
Even More Doc Cam Ideas Measure liquid in clear glass container Students take.jpg image of work. Build an electronic portfolio on USB drive Project missing assignments Essay Writing- Choose a few student essays. Cover name. Critique. Tell students “Your writing may be published at any time” Demonstrate dictionary skills Have off-task student work under doc cam. Make sure it’s work that has no right answer so doesn’t matter if others see Use as teleprompter when video taping projects
Even More Doc Cam Ideas Forgery- put parent signature under doc cam. Let class decide if forged. Show dissections Daily Activities to post: –Newspaper article of the day –Word of the day –Math problem of the day –Writing prompts –“On This Date” –Analogy of the Day –Picture of the day
Activity – Create a Lesson You have until 10:45 to collaborate with your team on a mini-lesson using the document camera. Limit lesson to 5-10 minutes. Your team will present the lesson to the rest of the class. Awards: –Most Engaging –Most Creative –Most Fun
